Isatin forms complexes with copper (II) containing this functional group that have been shown to interact with the mitochondrial apoptotic pathway. In glycolysis, there is an intermediate of this type in the fructose 1,6-bisphosphate aldolase catalyzed reaction.  A Mannich base undergoing hydrolysis yields a compound with this functional group. In Vitamin B6, the aldehyde group of the PLP cofactor attacks an (*) amino group to produce an intermediate with this functionality. They can be produced by the reaction of alkenes with hydrazoic acid via the Schmidt reaction, and in the aza Diels-Alder reaction, one of these reacts with a diene to form a tetra-hydro-pyri-dine. For 10 points name this functional group characterized by a nitrogen carbon double bond that is used as an electron sink in many reactions.
